Monaro vxr exhaust options
Discussion
Hi there, new to the forum, and need some advice. I have a 2006 vxr, with a wortec cat back fitted. Absolutely love the exhaust note, I just want it to be louder
the car is not used very often at all, and when I do drive it, it's purely to go for a blast and hear the v8 noise.
People who aren't in the car, comment on the noise, but it's not that loud inside.
I've been reading alot on the forums, about exhausts, and there seem to be lots of different opinions.
So, what is the best way to make it louder and keep the exhaust tone?
I read headers should make it louder in the car. Does it make a big difference? Is it worth it for the noise increase, if any? Not fussed on power increase really.
Lastly, what headers do people have fitted? Not sure I can afford wortec, so has anyone fitted the shorty headers from America? Or the pacemaker ones from Australia? Are they a straightforward swap?
Thanks everyone!

Welcome 
Have you tried opening the windows?
Headers do make it louder, but it's always going to be a lot louder behind you unfortunately. Cut-outs are a possibility for ultimate loudness, could have them installed shortly after the cats, that would bring the fairly ludicrous amount of noise much closer to where you're sitting, but you'll probably lose a lot of the 'tone' as it'll just be riotously loud. Will sound pretty stout at full chat though

Do you still have the centre silencers in on the cat-back as that'll make a fairly size able difference?
I had a CV8 with the Wortec Cat-back and no silencers - thought that was genuinely borderline on what I could get away with. Got some headers and high flow cats made up and had that fitted thinking it would just be a lump more power. The increase in noise was frankly staggering and much more than I was expecting, and it's a good noise too and like you, the car is driven to meets and for joy, not daily and I just think sod it - you only live once.
Cut-outs are a laugh, but you really can't get away with driving around with them open for long before you start attracting a lot of attention (not necessarily good) which is kinda probably not what you want.

IME headers will increase volume a bit, but most noticeably valvetrain noise. You've already got a stainless cat-back which is about the best sound option - I think any removed/bypassed silencers will only reduce quality, but may be worth it for the increase in volume. Removing the cats will make it considerably louder.
Hi there and welcome to the forum.
Like you I have the Wortec cat back system the switchable one and I can't decide if it's quiet or I'm just getting used to it now
As said already you can remove the cats and change the headers (something I'm doing at the moment) which will increase the noise.
I bought my headers from VPW in Australia.

I have an LS1 VXR and that has long tube headers, Wortec cat back, 100 cell cats and cam, and it's LOUD without the centre silencers. I drove 1000 miles one weekend for the national meet and it was quite a challenge with the noise, but enjoyable nevertheless. This type of set up will annoy neighbours, almost certainly. I've since put the silencers back in and it's still loud, but not quite as in yer face, and is ok inside the car. The car is used everyday.
Without the silencers it does create more noise as mud says, it's an acquired taste for a daily but it's good to have the choice!

Thanks very much for the help guys!! I've been looking at the cut out options, and have read alot about them over the Internet. Just wondering has anyone fitted and wired them in themselves? Any recommendations as to what type to go for if I did?

I know it's not on a monaro, but seems like it might work with a switchable backbox. I.e, make one section really loud, without haveing to permanently modify.

Headers will make a nice difference, when i got my monaro it had a wortec cat back with the switchable option, with it like that the quiet mode was quiet and loud mode was a nice level but without being too loud
I had the wortec headers fitted (along with other stuff) and now the quiet mode was like the loud mode before but the loud mode was a lot louder and i loved it

As he said /\ /\ /\ but without the switchable bit for me, so just loud to chuffing loud I had the wortec headers fitted (along with other stuff) and now the quiet mode was like the loud mode before but the loud mode was a lot louder and i loved it

Anyone had much experience with the shorty headers from the u/s? Are they much of an improvement?
LHD headers will not fit on your car without some cutting and shutting, I'm afraid.Welcome to the site - and the cheapest way to hear your car better, is to have your ears syringed.
